I was in a de facto relationship for 5 year, and had 2 kids and built a house together in that time. We split a year ago and the kids and I moved into the house we just built. We go 50/50 in the mortgage. My half comes out of my child support which is a privet agreement between the ex and I. But when the ex comes to see the kids, he stays at the house, showers here treats it like his own, and has recently be saying he wants to move down here and get a job, and he said he is moving into the house with us. What rights do I have with the house been the sole carer of the kids and paying equal amounts of the mortgage? The ex also wants to put the house in a family trust under the kids' names which I'm all for because it's for the kids, but if we do that, who then has the rights over the house until the kids are of age? They are only 2 and 3 years old at the moment. I just want to know where I stand as I don't want to live with my ex.
